Chocolate and Your Health: Good or bad?

Could Chocolate's Good rap be the Best Health News Ever?



Patients tell me that Easter is a favourite time for them as it's ok to have chocolate.

They seemed shocked and surprised when l tell that most days of the year are my favourite because they involve chocolate is some form or other. Truly one of my favourite subjects, and not just for Easter, and as part of a well balanced diet with good amounts of exercise each day, then some chocolate, especially dark chocolate may just be what some of us need and not have to feel too guilty about consuming.

With extensive world wide research in recent years looking into to the potential benefits of the cocoa bean and resulting product, chocolate having thrown up very interesting results, the euphoria surrounding this may well be justified, as has been highlighted already in 2012.

I was heartened (excuse the pun) by a study from Vanderbilt University Medical Centre in the US, where Vanderbilt Heart and Vascular Institute cardiologist Julie Damp, M.D and he team looked further into previous research of the heart health benefits of Dark Chocolate  and it's potential antioxidant affect of it's Flavonoids being good for heart health, which are also similarly present in Red Wine.

The research team in this instance back up a previous report from January this year from Susan Ofria, a registered Dietitian at the Loyola University Health System’s Melrose Park Campus, that looked specifically at the active component in Chocolate and Red Wine, Resveratrol, that provides that antioxidant potential and the benefits for health, such as in heart health.

Dark Chocolate may hold potential benefits to heart health

Dark Chocolate with a Cocoa content higher than 70% (I prefer to get my hands some amazing 85% chocolate) contains the beneficial levels of Resveratrol that may be beneficial to health as part of a well balanced diet and active lifestyle,  and is associated with lower blood pressure, lower blood sugar levels and according to these reports "improvement in the way your blood vessels dilate and relax," all with the potential to assist with health in the right circumstances.

As highlighted previously in this blog, scientific research has pinpointed Resveratrol for it's potential anti cancer abilities, prevents age related impairment, have a positive impact on obesity, it's anti-inflammatory, antioxidants affect that can at the same time increase blood flow and overall further reduce the risk of Cardio vascular disease (CVD), and may have potential benefits in regards Metabolic syndrome and dark chocolate and cocoa can now be added to the products that contain the naturally occurring antioxidant.

Further chocolate benefits studies have similarly suggested the potential for health in a well balanced diet, firstly, chocolate and heart health as highlighted by Dr Oscar Franco and colleagues from the University of Cambridge carried out a large scale review of the existing evidence to evaluate the effects of eating chocolate on cardiovascular events like heart attack and stroke.

 

And before that, Circulation: Heart Failure, a journal of the American Heart Association, reported the work of Murrray Mittleman, M.D., Dr.P.H., lead researcher of the study at the Cardiovascular Epidemiology Research Unit at Harvard Medical School's Beth Israel Deaconess Medical Centre in Boston, where links we made to weekly chocolate consumption with higher Cocoa content, usually found in Dark chocolate, or especially in European chocolate, potentially leading to lower risk of heart failure, as Dr Mittleman highlighting what we all really know...

"You can't ignore that chocolate is a relatively calorie-dense food and large amounts of habitual consumption is going to raise your risks for weight gain,".......But if you're going to have a treat, dark chocolate is probably a good choice, as long as it's in moderation."

Which Chocolate is Best?

By all accounts from the research detailed above and much more into the antioxidant content of chocolate and any potential health benefit it may have, it's dark chocolate that comes out on top in this regard, but along with comes research from Denmark, where scientists at the University of Copenhagen, Faculty of Life Sciences (LIFE) have shown that dark Chocolate may also be more filling than milk chocolate, giving a general feeling of satiety longer than milk chocolate and lessen the potential for food cravings, over-eating and consumption of too many calories.

With the calorific content the same for both milk and dark chocolate in the study, participants after the consumption of the chocolate ate significantly less in an subsequent meal and overall had less of an appetite for over eating too much on sugary, salty and fatty foods.

Dark Chocolate could reduce cravings, ease emotional stress and assist the Liver

And the potential benefits may not end there according to research highlighted in the American Chemical Society (ACS) Journal of Proteome Research, some Dark chocolate each day within a well balanced diet may help ease 'emotional stress' by a reduction in levels of stress hormones and other stress-related biochemical changes in volunteers who rated themselves as 'highly stressed' and were asked to eat dark chocolate for a two week period.

"The study provides strong evidence that a daily consumption of 40 grams [1.4 ounces] during a period of 2 weeks is sufficient to modify the metabolism of healthy human volunteers," 

 The beneficial Phytochemicals and Antioxidants qualities of dark Chocolate are also interesting researchers and scientists looking at the impact of Liver damage from cirrhosis and whether chocolate, especially high quality dark chocolate may help reduce damage.

The Spanish research team looked at results that showed dark chocolate consumption could

"reduce the postprandial (after-meal) blood pressure in the liver (or portal hypertension) associated with damaged liver blood vessels (endothelial dysfunction). "

 The damage done by Liver Cirrhosis can not only cause a dangerous raise of blood pressure levels in the Liver, but also elsewhere in the body leading to potential fatal consequences for health, however, Dark Chocolate consumption could provide some benefit.

Cocoa- A 'Super Fruit' ?

So with researchers and scientists alike highlighting the potential benefits of some daily consumption of dark Chocolate within a balanced diet and lifestyle on our health, some going so far to call Cocoa/chocolate a 'Super Fruit' that may be good for the heart, liver, blood pressure and our emotional state then one can start to see how great some of the 'dark stuff' may just be.

I for one shall continue to choose my Dark Chocolate well and try and enjoy some each day in between the fruits and Vegetables and the 15 minutes of exercise.

Happy eating!
